BOLT-CUTTER.

SPECIFICATION forming part of Letters Patent No. 275,015, dated April 3, 1883.

Application filed February 12, 1882!. (Model.)

To all whom it may concern:

Be it known that I, AZOR BLOWERS, of Oambridge,in the county ot'Lenawee and State of Michigan, have invented new and useful Improvements in Bolt-Cutters; and I do hereby declare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, which form a part of this specification.

The nature of this' invention relates to certain new and useful improvements in the construction ot'that class of implements which are employed for cutting off wire or other small metallic rods.

The invention consists in the peculiar construction of the various parts, and their combinations and operation, as more fully hereinafter described.

Figure 1 is a plan view of my improved device with the confiningplate removed. Fig. 2 is a cross-section through thejaws and knives.

In the accompanying drawings, which form a part of this specification, A represents one of the jaws, provided with an ear, 0, through which, and a similar ear upon the other-jaw, B, a bolt, 1), secures the two jaws together pivotally, while the same bolt also passes through the confining-plates (J, one being provided for each side of the device. The rear faces of the jaws A B are dovetailed to receive the knives D, having shoulders a to rest against the inclined sides of the jaws A and B, as shown in Fig. 2, while the front faces are cut away, the chamber E, formed thereby acting as a guide to facilitate the conducting of the wire to the knives when open. The outer ends of these jaws A B terminate in flat faces 0, by means of which the end of the wire may be grasped and twisted, as with a pair of pinchers. A

spring, F, is inserted between the arms of said jaws, the function of which is to compel the jaws to remain in an open positionexcept. when force is applied. For the purpose of applying this force to thejaws and compelling them to perform the functions designed, I provide two lever-handles, G and H, both of which are provided with ears (I, through which a bolt, 6, passes to pivot-ally secure such lever-handles together, while at the same time the bolt passes through the two confining-plates, and, with the bolt '1), firmly holds said confining-plates in place. Each of these handles, atits innerend, terminates in a cam-shaped lug, I, which engages with the circular recessesfupon the inner end of the jaw-arms. J is a stop rigidly secured to one of the. confining-plates to limit the travel'ot' the free ends of the lever-handles toward each other to prevent an undue strain upon the cutters or knives. 7

It is evident from this construction and operation of parts that the jaws provided with the dovetailed cutters may he extended-any length to form a pair of shear blades, and such extension of such blades would be within the spiritof the present invention.

This implement will be found very useful to those engaged in erecting telegraphic, telephonic, or other wires for electrical purposes, as when constructed as described it'l'urnishes not only the tool for cutting elf the wire when desired, but a pair of nippers or pinchers by means of which the end of the wire may be clasped and twisted at pleasure.

\Vhat I claim as my invention is- 1. The combination of thejaws A B, spring F, and handles G H with the bolts 1) e and confining-plates O, the parts being constructed and operating substantially as and for the pun poses set forth.

2. In a bolt and rod cutter, the combination of the jaws A 13, having plane faces 0, spring F, and cutters I) I), the latter having shoulders a, and dovetailed, in the jaws, substantially as described, with the confining-plates 0, bolts 1) e, and handles G H, all constructed and operating substantially as and for the pur pose set. forth.
